Abstract
This study aimed to evaluate cowpea genotypes for adaptability and stability of grain yield using different methods, in order to support the launch and/or cultivars recommendation for agribusiness in the Brazilian Midwest. Trials were conducted from 2010 to 2012 in four locations, totaling eight environments. We evaluated 20 cowpea genotypes arranged in a randomized block design with four replications. Studies of adaptability and stability of cowpea genotypes were estimated using different methods. The environments A1, A5, A6 and A8 are the most appropriate for selecting superior genotypes for adaptability and stability. The genotypes MNC03-737F-5-1 BRS-Tumucumaque, BRS-Guariba, MNC02-684F-5-6, MNC03-725F-3, MNC02-682F-2-6, BRS-Cauamé, BRS-Itaim and MNC03- 737F-5-11 showed adaptability and stability sufficient for recommendation for the region. Eberhart and Russell, Lin and Binns and AMMI methods can be used as a complementary way to better predict the genotype performance. Key words: Genotype, environment interaction, selection Vigna unguiculata.
